They designed a pixel that can not only measure incident light but also convert the incident light into electric power.
although digital cameras and solar panels have different purposes-one measures light while the other converts light to power-both are constructed from essentially the same components.
The same photodiode is used also in solar panels to convert incident light to electric power. The photodiode in a camera pixel is used in the photoconductive mode
while in a solar cell it is used in the photovoltaic model. Nayar, working with research engineer Daniel Sims BS'14 and consultant Mikhail Fridberg of ADSP Consulting, used off-the-shelf components to fabricate an image sensor with 30x40 pixels.

It uses something called HCPVT (Highly Efficient Concentrated Photovoltaic/Thermal) to generate electricity and hot water from solar power.
as well as highly efficient photovoltaic cells (known as gallium arsenide photovoltaic cells) to convert that concentrated solar energy into electricity. Though concentrated solar thermal power
and PVS are nothing new to the solar power industry, the Solar Sunflower incorporates these technologies in a novel way that represents a few ingenious engineering breakthroughs.
"In other words, the difference between this technology being classified as a death ray as opposed to a solar array is merely a matter of how the reflectors are angled.
Photovoltaic cells used by the Sunflower have a max operating temperature of around 105 degrees Celsius,
The end result is a device that produces about 12kw of electricity, along with 21kw of thermal energy.
Even though that doesn't amount to a huge amount of energy (the 12kw of electricity is only enough to power a few homes, for instance),
it is nonetheless highly efficient. The real obstacle to the implementation of the Solar Sunflower is its cost.
Its gallium arsenide photovoltaic cells though more efficient than standard PV cells, are not cheap. Add up construction costs and the costs of the fancy cooling system,
and the design isn't going to be able to financially compete with less innovative but sure-fire solar energy harvesters already on the market.

A new generation of organic semiconductors may allow these kinds of flexible electronics to be manufactured at low cost,
And then, with this enhanced view,"this energy barrier can be eliminated entirely, "the team writes.
the new research provides a powerful way to explore many other types of organic materials, too--with particular promise for improved solar cells.
A recent U s. Department of energy report identified one of the fundamental bottlenecks to improved solar power technologies as"determining the mechanisms by
which the absorbed energy (exciton) migrates through the system prior to splitting into charges that are converted to electricity."
--and can't be pushed by voltage like the electrons flowing in a light bulb--they can, in a sense, bounce from one of these tightly stacked molecules to the next.
This allows organic thin films to carry energy along this molecular highway with relative ease,

who directs UVM's program in materials science, "and to do that we need a deeper understanding of exciton diffusion.

#Harvesting energy from electromagnetic waves (Nanowerk News) For our modern, technologically-advanced society, in which technology has become the solution to a myriad of challenges,
energy is critical not only for growth but also, more importantly, survival. The sun is an abundant and practically infinite source of energy,
so researchers around the world are racing to create novel approaches to"harvest"clean energy from the sun or transfer that energy to other sources.
This week in the journal Applied Physics Letters("Metamaterial electromagnetic energy harvester with near unity efficiency"),researchers from the University of Waterloo in Canada report a novel design for electromagnetic energy harvesting based on
the"full absorption concept.""This involves the use of metamaterials that can be tailored to produce media that neither reflects nor transmits any power--enabling full absorption of incident waves at a specific range of frequencies and polarizations."
"The growing demand for electrical energy around the globe is the main factor driving our research,
"More than 80 percent of our energy today comes from burning fossil fuels, which is both harmful to our environment and unsustainable as well.
In our group, we're trying to help solve the energy crisis by improving the efficiency of electromagnetic energy-harvesting systems."
and harvesting electromagnetic energy, classical dipole patch antennas have been used.""Now, our technology introduces'metasurfaces'that are much better energy collectors than classical antennas,
"explained Omar M. Ramahi, professor of electrical and computer engineering. Metasurfaces are formed by etching the surface of a material with an elegant pattern of periodic shapes.
The particular dimensions of these patterns and their proximity to each other can be tuned to provide"near-unity"energy absorption.
This energy is channeled then to a load through a conducting path that connects the metasurface to a ground plane.
The key significance of the researchers'work is that it demonstrates for the first time that it's possible to collect essentially all of the electromagnetic energy that falls onto a surface."
"Conventional antennas can channel electromagnetic energy to a load --but at much lower energy absorption efficiency levels,"said Ramahi."
"We can also channel the absorbed energy into a load, rather than having the energy dissipate in the material as was done in previous works."
"As you can imagine, this work has a broad range of applications. Among the most important is space solar power,
an emerging critical technology that can significantly help to address energy shortages. It converts solar rays into microwaves--using conventional photovoltaic solar panels--and then beams the microwave's energy to microwave collector farms at designated locations On earth.
Japan is way out in front of rest of the world in this realm, with plans to begin harvesting solar power from space by 2030."
"Our research enables significantly higher energy absorption than classical antennas, "Ramahi said.""This results in a significant reduction of the energy harvesting surface footprint.
Real estate is a precious commodity for energy absorption --whether it's wind, hydro, solar or electromagnetic energy."
"Other key applications include"wireless power transfer--directly adaptable to power remote devices such as RFID devices and tags or even remote devices in general,"Ramahi noted.
The technology can also be extended to the infrared and visible spectra.""We've already extended our work into the infrared frequency regime
and we hope to report very soon about near-unity absorption in those higher-frequency regimes,"added Ramahi i

#MIT Invention Turns Salt water Into Drinking water Using Solar power From plants to people, every living thing on this planet needs water.
The group came up with a method that uses solar panels to charge a bank of batteries.
The batteries then power a system that removes salt from the water through electrodialysis. On the most basic level, that means that dissolved salt particles,
which have a slight electric charge, are drawn out of the water when a small electrical current is applied.
but powering sensors--even really efficient sensors--requires some form of electric charging or battery replacement.
Renewable energy is tricky in tunnels, since the sun's rays don't reach that far. But each GENESI node and sensor includes a miniature wind turbine that harvests energy from passing trains.
For all other sensors, whether tucked away in tunnel walls or nestled in dark unlit crevices under bridges,
replacing batteries isn always the easiest task for humans, so that might be a future job for drones.
Currently cars are pieced together on long assembly lines inside large factories that use massive amounts of energy.
